It is used to quantitatively determine the content of albumin (mALB) in human urine. Albumin is one of the important plasma proteins. Under normal circumstances, albumin has a large molecular weight and cannot cross the glomerular basement membrane. Therefore, the urine of healthy people contains only a very low concentration of albumin. When the glomerular basement membrane is damaged, the concentration of albumin in the urine will continue to increase, resulting in microalbuminuria. Urine albumin determination has higher specificity and sensitivity than total protein for early detection of renal function changes and subsequent treatment monitoring. In predicting diabetes, urinary microalbumin has been used for many years, and it has become an important indicator for observation of diabetic nephropathy and evaluation of curative effect. The reference interval is random urine: <30mg/g creatinine
